Description

Summary: The design, construction and assembly of all components were completed during the first contract year previous to December 1963. These efforts, defined by Tasks A-F, are document in (1), (2), and (3). Brief summaries of these completed efforts are given in the introduction to each of the tasks in the text of this report. The digest given below covers only the shakedown and analysis work carried out in the fourth quarter of the first contract year.
Task G Shakedown Tests. The photographic procedure has been experimentally defined for the glass test section. Four automatic 35 mm cameras and four strobe light sources have been ordered on ATL funds and their respective mounting arrangements are in place. Roughly ten test runs were carried out in the glass test section during the course of the above work. Satisfactory recorder traces have been obtained on all measurement systems. These systems presently meet the accuracy and linearity specifications initially set. An x-ray void fraction signal adjustment and filtering circuit has been design and installed to provide equal resolution across the test section. Calibration disc inserts have been installed to permit satisfactory beam intensity calibration. Good agreement has been obtained between calculated and measured beam intensity profiles across the test section. To improve the flexibility of the differential pressure measurement system, zero suppression up to 1.5 psi has been calibrated for each bridge circuit. This makes up for the fact that the reference pressure control regulator does not quite meet the vendors dead band specifications. To facilitate the initial records chart calibration for the temperature sensors a special precision decade box switching circuit has been installed. While no significant temperature sensor calibration shift has taken place in two months, the lack of adequate reliability of these units will require a periodic calibration check. Negotiation with the vendor is in progress to improve the reliability of the spare units on hand. The power supply for the metal test section has achieved the specifications set for it under both steady state and oscillating heat input. A maximum input of 3.5 KW has been employed to date. The power input sensor has been constructed and installed so that the test section voltage, current and/or power input can be instantaneously recorded. Considerable experimental work has been completed to determine the many calibrations and operating procedures required. On the whole, except for the inadequacy of the vendors temperature sensor calibration, the shakedown effort and materials required have been reasonable without encountering major delays. As a result, the scope effort proposed for the first contract year will have been completed by March 18, 1964, within the initially estimated cost.
